BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a joining structure of an upper corner piece and rod parts of a baby mesh bed, more particularly one, which prevents the joints between the upper corner piece and the rod parts from being exposed, and allows the rod parts to be easily separated from the upper corner piece for maintenance, repair and replacement of cloth and mesh members and the joints of the mesh bed.

2. Brief Description of the Prior Art

FIG. 10 is an exploded perspective view of a traditional joining structure of an upper corner piece 91 and upright and transverse rod parts 93 and 92 of a baby mesh bed. The upper corner piece 91 comprises single part, and is angled to have an angle portion. The upper corner piece 91 has a receiving section 911 inside the angle portion, and holding rooms on two sides of the angle portion. The upright rod part 93 is inserted in and securely joined to the receiving section 911 of the upper corner piece 91. The transverse rod parts 92 are each held in a corresponding said holding room at a first end with a pivotal hole, and pivoted on a pivotal element 921 passed through the pivotal hole thereof as well as connecting holes of the upper corner piece 91. Therefore, the transverse rod parts 92 can be angularly displaced relative to the upper corner piece 91.

The above structure has the following drawbacks: the pivotal elements 921 stick out from two sides of the upper corner pieces at two ends thereof to spoil the appearance of the upper corner piece. And, in assembly, it will take some much time to adjust position of the transverse rod parts 92 in order for the pivotal holes of the transverse rod parts 92 to face corresponding connecting holes on the upper corner piece 91 to allow the pivotal elements 921 to pass through. Therefore, the above structure is relatively slow to assemble.

It is a main object of the present invention to provide an improvement on a joining structure of an upper corner piece and rod parts of a baby mesh bed to overcome the above problems.

A mesh bed according to an embodiment of the present invention; the upper corner piece includes an upper corner piece, and rod parts. The upper corner piece comprises an inner and an outer wall portions at each of two end portions thereof, internal rooms between the inner and the outer wall portions, and an internal sleeve portion securely disposed between the internal rooms. The rod parts include two transverse rod parts; the transverse rod parts are each pivoted to one coupling piece, which is held in one said internal room of the upper corner piece, and securely joined to the sleeve portion of the upper corner piece by means of fixing elements. The rod parts include an upright rod part, which is also securely joined to the sleeve portion of the upper corner piece at an upper end by means of the fixing elements.

Therefore, the joints between the upper corner piece and the rod parts of the mesh bed are covered with the upper corner piece instead of being exposed, without spoiling the appearance of the upper corner piece. And, after the fixing elements have been loosened, the upright rod part and the coupling pieces with the transverse rod parts can be separated from the upper corner piece in order for cloth and mesh members and the joints of the mesh bed to be repaired, maintained, and replaced.

The upright rod part 6 further has a fitting portion 62 on an inner side of a corner thereof, which is inserted in the fitting groove 543 of the sleeve portion 541 of the upper corner piece 5.

Each of the transverse rod parts 8 has a pivotal hole (not numbered) at a first end thereof, and is pivoted to a coupling piece 7; each coupling piece 7 has an upright end wall portion 71, two connecting wall portions 72 projecting from two sides of the end wall portion 71, and a pivotal hole 721 on each of the connecting wall portions 72, as shown in FIG. 6; each coupling piece 7 further has a protruding portion 74 sticking rearwards from a rear side of the upright end wall portion 71 thereof, which protruding portion 74 is in the shape of a “T”, and which has a through connecting hole 741 thereon. Each of the transverse rod parts 8 is pivoted to a respective said coupling piece 7, with the first end thereof being received between the connecting wall portions 72 of the coupling piece 7, and with a pivotal element 73 being passed through the pivotal holes 721 as well as the pivotal hole of the transverse rod part 8.

In assembly, referring to FIGS. 7, 8, and 9, each of the coupling pieces 7 with a corresponding said transverse rod part 8 is positioned in one of two end portions of the internal room 53, with the protruding portion 74 being inserted in a corresponding said groove 541 of the sleeve portion 54 of the upper corner piece 5. Next, the upright rod part 6 is positioned around the sleeve portion 54 of the upper corner piece 5 at the upper end thereof, with the fitting portion 62 thereof being inserted in the fitting groove 543 of the sleeve portion 541. And, fixing elements 75 are passed through the through holes 61 of the upright rod part 6, the through connecting holes 741 of the coupling pieces 74, and the fixing holes 542 of the sleeve portion 54 of the upper corner piece 5 so as to secure the coupling pieces 7 to the sleeve portion 54 as well as the upright rod part 6. Therefore, the transverse rod parts 8 pivot on the upper corner piece 5.

Therefore, after the fixing elements 75 have been loosened by means of a tool, the upright rod part 6 and the coupling pieces 7 with the transverse rod parts 8 can be easily separated from the upper corner piece 5 in order for cloth and mesh members and the joints of the mesh bed to be repaired, maintained, and replaced with a new one.
